Hi, I have this Lenovo chromebook and I followed the installation steps for the Acer Chromebook R13 since they were similar enough, and everything seems to work so far, including wifi; however, there are dumps about syscall 439 (faccessat2?) and some others, so I figure they're not fully compatible. I have also found this link
https://lore.kernel.org/linux-arm-kernel/CAJMQK-geKkDJF0QtScf+=gLnpYhyLDQHvSM-aYkxsczZvJVsVQ@mail.gmail.com/ which seems to be talking about my device in comparison to the Acer Chromebook R13.
